Experimental release channel

As explained in Kubernetes in Action, Second Edition

The experimental release channel contains Gateway API resources and fields that may change in future API versions.

The experimental release channel contains additional Gateway API resources and fields that may change in future API versions. Choose it when installing the Gateway API Custom Resource Definitions (CRDs) to access features beyond the stable standard channel. section 13.1.2

The channel affects API stability, not implementation support:

  • The standard channel contains resources and fields considered stable and not expected to change in future API versions. section 13.1.2
  • The experimental channel adds resources and fields that remain subject to future change. section 13.1.2
  • Both stable and experimental features can separately be classified as core, extended, or implementation-specific according to implementation support. section 13.1.2

Choosing a channel

When installing Gateway API CRDs, select the experimental channel if the configuration needs a resource or field not included in the standard channel. At the described point, HTTPRoute is standard while other route kinds remain experimental. section 13.1.2

How Kubernetes in Action, Second Edition covers it

How deep it goes
Defines channel stability and distinguishes it from implementation support, but does not detail installation commands.
Examples
Uses HTTPRoute as a standard-channel example and other route kinds as experimental examples.
What it assumes
Assumes familiarity with Gateway API resources and CRDs while defining release-channel stability from the beginning.
What you can do after
Operate/configure Gateway API CRDs by selecting stable or experimental resources according to change tolerance.
How it connects
Connects Gateway API, Custom Resource Definitions, standard release channel, and core, extended, and implementation-specific features.
